THE GREEN SUN STORAGE HYDRO POWER PROJECT

The Green Sun Storage Hydro Power (GRSSHPR - "Grasshopper") Project is a 325 mile, water/renewable energy infrastructure system from the Flaming Gorge/Green River System in SW Wyoming through the Interstate 80 Federal Energy Corridor into the Front Range of Colorado. The water transmission project will provide water supplies into Colorado, new water storage for the region, and 15 megawatts of in-pipe hydropower produced from a net fall in elevation. The Projects’s water deliveries will create benefits for environmental in-stream flows, wildlife conservation, agricultural expansion, and municipal use.

The legal use of water from the Green River and Flaming Gorge Reservoir to benefit Colorado users is part of the policy, institutional, and legal framework of the Colorado River Compact (1922) and Upper Colorado River Basin Compact (1948) which distributes water supplies in the western United States. 

The Green River System is unique, with environmental flows and fisheries fully and legally protected by a previous National Environmental Policy Act/ Environmental Impact Statement (NEPA/EIS) Record of Decision (ROD). Spearheaded by the Nature Conservancy, the Federal EIS/NEPA Record of Decision (ROD) re-regulated the expansive 3.8 million acre-foot Flaming Gorge Reservoir to assist downstream recreation and fisheries. Extensive modeling accomplished by the Bureau of Reclamation, the federal agency that manages the water supply, combined with other 3rd party analysis, all indicate a major surplus of water above the environmental and recreational needs in the Green River. The surplus is intended to assist other water-short areas, in this case the Colorado Front Range, while fully protecting the environmental benefits on the Green River System, the largest tributary to the Colorado River mainstem.
